【摘要】 索托结构是我国自行开发的一种新型结构形式 ,其外形类似斜拉结构但受力性能则完全不同。其受力特点与悬索结构有相似之处 ,故集中了斜拉结构和悬索结构的优点 ,克服了它们的不足之处。目前国内外超跨度结构仅有斜拉和悬索结构两种 ,且都存在许多缺点。索托结构因其斜索效率大大改善 ,受力更为合理 ,故可节省用材和工程造价 ,其跨越空间的能力比斜拉和悬索结构均优 ,且施工方便更多还原

【Abstract】 The cable supported structure is a new kind of structure developed by ourselves. It looks like the cable stayed structure, but its mechanical characteristics is quite different. This structural system has all advantages of cable stayed structures & suspended structures and overcomes their shortcomings. It can save a lot of engineering materials and cost of construction becouse its structure is reasonable in the view of point of mechanics. At present, there are only two types of long span bridges—cable stayed bridges ( L ≥500m) and suspended bridges ( L ≥1000m). Since cable supported structure improves the efficensy of cables and decreces the hight of towers greatly, this kind of structure can save a lot of materials. At the same time, its crossing capasity is biger than that of cable stayed structure & suspended structure and easier to erect.更多还原
